Can you move house while you have a mortgage?

If you’re in the middle of a mortgage term and you’re ready to move, the key question is usually the same: can you take your existing mortgage with you, or do you need to change it?

In many cases, yes—but the best route depends on what you’re doing with your current property (moving into it, renting it out, or using it as a second home), and on what your lender is willing to do.

This guide explains the main options available to home movers, what lenders typically consider, and the practical points that can affect whether your plan is straightforward or more complex.

The main options for moving home with an existing mortgage

When you already have a mortgage and want to buy somewhere else, there are four common approaches.

1) Port your existing mortgage (transfer it to a new property)

Mortgage porting means moving your current mortgage deal from your existing home to your next one, keeping the original terms (subject to lender approval).

Why people port:

• It may help you avoid an early repayment charge.
• It can be useful if your current deal is particularly competitive.

What to watch:

• Porting isn’t always automatic. Some lenders reassess the mortgage as if it were new borrowing.
• Even if the interest rate is retained, lenders may still review affordability based on your current circumstances.
• If you want to borrow more than your current balance (for example, to fund a higher purchase price), you may need additional borrowing (often referred to as a “top-up”).

2) Remortgage (take a new deal with your current lender or another lender)

Another option is to end your existing mortgage arrangement and set up a new one for the property you’re buying.

Why people remortgage:

• It can give you flexibility if porting isn’t available or isn’t suitable.
• It may allow you to adjust the term or structure of the mortgage.

What to watch:

• You may face costs such as early repayment charges, arrangement fees, valuation fees, and legal fees.
• If you move to a more expensive home, you may need to borrow more, which can change the overall affordability picture.

3) Let-to-buy / consent to let (rent out your current home while you buy again)

If you want to move but keep your current property, you may be able to ask your lender for permission to rent it out temporarily.

This is often referred to as consent to let and is commonly used as part of a let-to-buy plan.

How it typically works:

• You request permission from your existing lender to let the property.
• You then arrange a separate mortgage on the new property you’re buying.

What lenders usually look for:

• Whether the proposed rental income is sufficient to cover the mortgage repayments.
• The reason for letting (lenders generally expect it to be genuine and not simply a way to avoid residential lending rules).
• Whether the property type and condition are acceptable for letting.

What to watch:

• Not all lenders allow consent to let in every situation.
• There may be an arrangement fee for the consent.
• If consent to let isn’t approved, you may need to consider an alternative approach (for example, remortgaging on a buy-to-let basis).

4) Keep your mortgage and use the property as a second home or holiday let

In some scenarios, you can keep your existing mortgage and move on to your next home while treating the original property as a second home or holiday let.

What lenders typically consider:

• Whether you can afford the ongoing costs of both properties.
• How the lender views any rental/holiday income (if applicable) and whether it can be used in the affordability assessment.

What to watch:

• This route is not the same as let-to-buy. Lenders may treat the overall situation differently.
• If the property is not genuinely intended to be used as a second home/holiday let, lenders may not accept the arrangement.

How soon can you move after taking out a mortgage?

There’s no single universal rule that applies to every lender and every mortgage product. However, lenders generally expect the mortgage to be used for its intended purpose.

In practice, lenders may be cautious if:

• You purchase a property and quickly try to switch it into a rental arrangement without a genuine reason.
• Your plan looks like it could be designed to bypass residential mortgage rules.

Other factors that can affect your ability to move include:

• Whether you have enough equity to support the next purchase.
• Whether your circumstances have changed since the mortgage was agreed.

Moving to a cheaper or more expensive property

If you’re moving to a cheaper home

Moving to a cheaper property can sometimes make the affordability picture easier, but it still depends on your overall finances and the mortgage structure.

If you’re looking to release equity to help fund the move, the lender will assess whether borrowing is appropriate and affordable.

If you’re moving to a more expensive home

A higher purchase price often means borrowing more, which can affect which option is practical.

If your lender won’t allow consent to let on your existing mortgage, you may need to consider remortgaging on a different basis.

Additional borrowing may be possible in some cases, but it’s not guaranteed and may not be available on the same terms as your original mortgage deal.

Can you have two mortgages at the same time?

It’s possible to have two mortgages concurrently, but it depends on whether you can meet the lender’s affordability checks.

There are two broad ways lenders may view the situation:

• You can afford the repayments on both mortgages from your income.
• The repayments on at least one mortgage are supported by rental income (where the lender accepts it for affordability).

Even if two mortgages are possible, the most suitable strategy still depends on whether your existing mortgage can be retained, whether consent to let is available, and what costs you might face if you need to switch deals.

Equity, negative equity, and why it matters when you move

If your property value has fallen since you bought, you may have less equity than you expected.

That can make moving more difficult because:

• You may not have enough equity to cover the costs of the move.
• If you’re in negative equity, lenders may be more restrictive about options like porting or additional borrowing.

Key points to consider before you commit to a plan

Before you decide which route to take, it helps to check:

• Whether porting is available for your specific mortgage and circumstances.
• Whether your lender will consider consent to let (and what conditions apply).
• Whether you can afford the new mortgage alongside the existing one.
• What costs may apply if you need to remortgage or change the mortgage basis.
• Whether your plan is consistent with the lender’s expectations for residential lending.

Summary: can you move house while you have a mortgage?

Yes—you can move house while you have a mortgage, and the most appropriate option usually falls into one of these categories:

• Port your mortgage to avoid switching deals (where available and approved).
• Remortgage to take a new deal for your next home.
• Use consent to let / let-to-buy if you want to rent out your current property.
• Keep your existing mortgage if you’re using the property as a second home or holiday let.

The practical differences come down to lender permissions, affordability, and whether your intended use of the current property fits the mortgage product.
